Rivastigmine capsule
Rivastigmine patch
Rivastigmine capsules starting at a total dose of 3 mg/day (1.5 mg twice daily orally) titrated up in 3 mg/day increments every 4 weeks to a final dose of 12 mg/day (6 mg twice daily orally). The 12 mg/day dose or the highest dose tolerated was maintained until week 76.
Rivastigmine patch once a day in the morning, worn for 24 hours, starting at 5 cm^2 (delivering 4.6 mg rivastigmine over a 24 hour period) for 4 weeks then titrated up to 10 cm^2 daily (delivering 9.5 mg rivastigmine over a 24 hour period). The 10 cm^2 patch or the highest well tolerated dose was maintained until week 76.
